**Problem**
Current MixedAnalyzingCompiler analysis cache caches using the last write,
assuming all writing happens via it. However, this doesn't work with
sbt 2.x caching system where the gz file under it can switch.
**Solution**
This switches to using caffeine caching, which includes file size
and file timestamp for local analysis caching.
Bumps io to released 1.12.0 which contains the atomic-write changes
to IO.copyFile, IO.transfer(InputStream, File), and IO.jar/zip.
ActionCacheStore.putBlob now uses IO.transfer instead of duplicating
staging logic.
**Problem**
Scala 3.8 REPL won't work since they've split the repl artifact into another JAR.
**Solution**
This works around it by creating a yet-another sandbox configuration ScalaReplTool
(similar to ScalaTool and ScalaDocTool) and a separate scalaInstance for
console task, so when Zinc is invoked we'll be able to conjure the right array of JARs.
**Problem**
sbt currently does not support JDK 25 Main class. JDK 25 supports:
1. non-public main method
2. doesn't need Array[String] arg
3. doesn't have to be a static method
**Solution**
This updates Zinc, which supports new Main class detection.
In addition, this implements in-process run emulation support.
**Problem**
Scala 3.8.0 nightly and later in-sources the scala-library for the use by Scala 3, as opposed to using Scala-2.13-bound standard library.
This means that we will run into situations where scala-library should NOT align with scala-reflect, which might exist transitively.
**Solution**
Adjust the csrSameVersions rule for Scala 3.8 so it will only try to keep scala-library and scala3-library versions aligned.
